The triangles below are congruent, with △ABC ≅ △DEF. The following lengths are given in centimeters: AB= x + 1, AC= x, BC= x + 2, and DF= 3x − 8. What is the value of x? PLEASE!!!

The triangles below are congruent with ABC DEF The following lengths are given in centimeters AB x 1 AC x BC x 2 and DF 3x 8 What is the value of x PLEASE class=

Respuesta :

x is 4.

AC = DF

Substitute:

x = 3x-8


Combine like terms:

x - 3x = -8
-2x = -8


Divide both equations by -2.

x = 4


I hope this helps. :-)
